TPMS Programming Troubleshooting
- Thread starter MiWiAu

Is anyone aware of a way to clear any possible TPMS DTCs? I don't see any stored or pending codes through my standard OBDII scanner, so I assume these are stored elsewhere (BCM?) and require Ford IDS/VCM to read?
Is there a way to force-clear any stored TPMS codes without a special dealer interface, like disconnecting the battery, KAM reset, etc?

Ford does have two TPMS's, a 315 MHZ and a 433 MHZ. Maybe got the wrong one?

Do you know what the frequency the 2013 Explorer is supposed to use?
I checked the imprint on the actual sensors I received, and they all read 315 MHZ, which I thought was correct, but I'm not 100% positive.
EDIT (01/10/17): I've tried using KAM reset to clear TPMS codes a couple more times, and continue to get a flashing light. I think my above experience with losing the TPMS light after a KAM reset was coincedental.

Do you have a link? From my FSM, I cross referenced the p/n for the OEM activation tool, and it appears to have been superseded by what appears to be the ATEQ VT-30 tool. However, I cannot find it for less than $175 online.
I have the OEM Ford TPMS19 training tool that I got for ~$30, but evidently it doesn't have the ability to wake/activate new sensors, only retrain sensors to new positions that have already been paired to the BCM.
Thanks, Jim!

No worries. It's hard to find good info on the logic and operation of the system. From what I can gather, brand new sensors that have never been programmed require a low frequency (somewhere around 125 kHz) to wake them up, which I suspect the TPMS19 tool is not capable. Once things go wireless, it might as well try reading Chinese.

Well, to add another layer of confusion, I ended up ordering the ATEQ VT30 service tool to see if I could resolve this myself before going to the dealer.
The VT30 reads all four sensors, pulls the sensor ID, reads pressure, Batt OK, and confirms they are 315MHz.
Still can't get these damn things to pair to the BCM in training mode.
Guess I won't be able to avoid the dealer trip. :/

Not sure about selling these things. LOL. It was actually pretty sweet just walking up to the tire, hitting the "read" button and getting a digital pressure readout within 0.25 PSI. Lazy, but sweet.
It very well could be some sort of interference, but if that's the case, I would expect the source to be on-board the vehicle. I've tried doing the learning in multiple locations, including out in the corn fields, and I'm not aware of any on-board auxiliary devices or wiring that could possibly be causing this. Hopefully the dealer can figure it out for a reasonable cost.
I read somewhere that the BCM can store up to 8 sensors (2 sets of wheels), though I couldn't find any mention of this in the service manual. If that's true, I wonder what would happen if the previous owner had a second set of wheels, or had new sensors installed when the tires were replaced.
If the additional "slots" in the BCM were taken up, would programming new sensors boot the oldest stored codes in the BCM, or would a manual clearing of the BCM be required to free up the memory?
At any rate, I wrote down all the sensor codes for both my new PI wheels and the OE 20" and will take them with me to the dealer along with my scan tool, just in case.
Now to go reload the OE tune, just in case they do something dumb like reflash the PCM.
Hopefully I will be able to post a root cause tomorrow after my dealer visit.Dang Mike this is turning out to be a very expensive set of winter wheels..MiWiAu said:SHOdded said:
If anyone can confirm if the paid version of Forscan has that capability, I'd gladly purchase.
I'll back in check in tomorrow.

Can you loan me some money? Lol It's all good and more tools and equipment is always good

SMH. Had to go show the Ford "technician" how to use the TPMS service tool. Don't have a great feeling about this. LOL
I think think the first two guys were their oil change specialists. They called over a guy who was plugging in the scan tool for further diagnosis. Fingers crossed...
